IMPROVEMENT IN HORSE-SHOES.

tterlgcmlc mami: tu im time trttcrs ntent rmt linking tart uf tige sume.

Be it known that I, BENJAMIN R. WATSON, ot' New Bedford,.iu, the county 0E Bristol, and State of Massa.- chusetts, have invented u new and useful Improvementin Metallic Shoes for Animals; and I do hereby declare that the ilellowing is` a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists in the mode set forth'for securing movable calks in metallic shoes.

Figure I is a perspective view ci' a horse-shoe, with the calks athxed by .my invention.

Figure 2 is a perspective view with the calks removed'.

Figures 3, 4, and 5 are respectively lmelc, side, and bottom views of one of the heel culks.

Fig. 1. Al is the shoe; Bl B Bl are the calks; Cl Cl Cx are the screws by which the calks are held iu-the mortses; d all dl, etc., are nail holes. l

Fig. 2. Az is the shoe; l)z D2 D2 are tapering dove-tn-il--lno1-tises, en'.l through thc shoes; e2 22e2 are holes for the screws shown by Cl, fig. 1; flfzf2 nrevrecesses cut into the shoe to admit the calks into the mcrtises.

Fig. 3. F3 is a. back view oi' a) heel calk, showing the dove-tail tenen and shoulder. l i

Fig. 4. B" is a side view of n heel calk; E4 shows the end cut off obliquely, against which the head ofthe screw presses to hold the calk tightinthe mortise, as shown in fig. 1. v

Fig'. 5. Gr5 is n bottom view of a. heel calk, and shows thc tapering or wedge-shape of the dom-tail tenori.

Operation.

Metallic shoes for animals, being forged or cast with tapering' dove-tail mortises, as shown and described, (see iig. 2,) the calk forged or east with tapering dovetail tenons, as also shown, l(see figs. 3 and 5,) the novelty of securing the calks in the shoes may be noted. Take the calk, lig. 5, and put it in mort-isc Dz, (see lig. 2,) so. that end :v2 will cover recess f2. y forcing it back, the tapering tenon shown liy G5, (see fig. 5,),and the dovetail shown hy F3 (see fig. 3) `bind and secu'rethe calks in the mortises. The screws C' Cl, ctc., have conical beads on theirunder sides, (not showin) which are of the same angle as the oblique end F, (sec lig. 4,).nnfl being :et down against the ends of the calks, prevent them from starting. Thus, the tapering dove-tail tenon callis are held firmly in the tapering doveftail mortises by the conical heads of the screws set against the ends of them. The ealks being one-eighth of an inch shorter than the mortises, may be tightenedv by driving them further in and setting down the screws to hold them. .I do not conneto screws for ,holding and tightening the ealks--they i may be held and tightened with screws asfhereinshown, or by any practical device; nor to cutting the mortises through the shoes-they may he cui partially through; neither do I claim anydevice previously invented or patented for securing celks in metallic shoes', but what Idoelaim as my inventiolnand desire to ser-.ure by Letters Patent, is l Securing calks in metallic shoes by fitting them with tapering dove-tail tenons to tapering dove-tail mor,- tises cut through the shoes, and tightening them by screws or their equivalent-s, as set fortli and described.
